Dr Atul Verma is the director of cardiology for the McGill University Health Centre and McGill University and is also the Isadore Rosenfeld Chair in Cardiology. He is a full Professor of Medicine. He is an electrophysiologist with an interest in complex ablation, particularly for AF and VT; new technologies; and clinical trials. He has over 300 peer-reviewed publications including in the New England Journal of Medicine, JAMA and the Lancet. He is currently an international expert in pulsed field ablation and other novel technologies for cardiac ablation. He has also served as Chair or on the Writing Committee of both national and international guidelines for AF.

Prof. Dr. Natasja de Groot, cardiologist-electrophysiologist is appointed at Erasmus University Medical Center and Delft University of Technology. She is chief of the research unit Translational Electrophysiology, Department of Cardiology. Her research focuses on unravelling the electrical mechanism of cardiac arrhythmias, particularly arrhythmias in (pediatric) patients with congenital heart disease and (post-operative) atrial fibrillation. For this purpose, she has developed unique signal recording and processing technologies. With insights obtained from these technologies, she develops, tests and implements novel diagnostic instruments and therapies. She is a Fellow of the EHRA, co-chair of EHRA 2025 and is involved in writing various international guidelines of the European Society of Cardiology, European Heart Rhythm Association and Heart Rhythm Society. In her clinical work, she focuses on ablation therapy of patients with congenital heart disease and atrial tachyarrhythmias.

Dr Louise Segan is a Cardiologist and Electrophysiologist at The Alfred Hospital in Melbourne, Australia, with a special interest in atrial fibrillation (AF) management. She is undertaking a PhD focusing on rhythm control strategies for patients with AF and left ventricular systolic dysfunction (LVSD). As part of her research, Dr. Segan played a central role in coordinating two landmark randomized controlled trials — the CAMERA-MRI II and WITHDRAW-AFstudies — both designed to explore therapeutic approaches to improve clinical outcomes in higher-risk populations. Her work has contributed to a growing body of evidence supporting the role of catheter ablation in heart failure and arrhythmia management. Dr. Segan remains actively involved in clinical research, medical education and mentoring, with a commitment to bridging the gap between evidence-based medicine and real-world patient care.

Dr Kenneth Cho is an electrophysiology fellow at the Alfred Hospital and PhD candidate with The Baker Heart and Diabetes Research Institute, University of Melbourne. His research is supported by the NHMRC Postgraduate Research Scholarship and focuses on improving outcomes for patients with atrial fibrillation.

Sam is cardiac physiologist and PhD candidate with the Complex Arrhythmia Program at Westmead Hospital, Cardiology Department and Westmead Applied Research Centre, The University of Sydney. His research interests lie primarily around arrhythmias, including screening, diagnosis and management in both the clinical and community setting.

Shalini Vijeyakumar is a fourth year medical student at the University of Sydney who is passionate about cardiology. Eager to contribute to the field of research, she completed her project under the supervision of Dr Qian and Dr Balaji at the Cardiology Department in Westmead Hospital.

Dr Karin Chia is a senior cardiac electrophysiologist and Director of the CIED Clinic at Royal North Shore Hospital in Sydney, Australia. Her clinical interests encompass catheter ablation of complex arrhythmias and the implantation and management of cardiac devices.
